Is Q235D carbon steel plate sheet or Q235B steel stronger?

We are a popular factory, supplier and wholesaler of mild steel plates and alloy steel plates in all over the globe. We follow all standards and specifications of Q235D carbon steel plate sheet boiler steel plate, structural steel plate, shipbuilding steel plates and corten steel in different types. We manufacture and supply steel plates, steel section and steel structures according to customer’s demand. The company also focus on providing customers with Q235D carbon steel plate sheet high-end steels and competitive price.

Wear resistant steel plate Q235D carbon steel plate sheet is an important material for industrial application. The traditional wear resistant steel is the high manganese steel which hardens under the impact load. The premise of its function must be subjected to enough impact load. With the development of wear resistant steel technology, NM series steel plate breaks through the limitation of traditional high manganese steel and realizes the application space of wear-resistant steel. The main Q235D carbon steel plate sheet grades of NM series wear resistant steel plates are NM360, NM400, NM450, NM500, NM550, NM600.

After quenching and tempering, 40Cr alloy steel plate and Q235D carbon steel plate sheet sheet have good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel Q235D carbon steel plate sheet is good. It can be hardened to Ф28 ～ 60mm during water quenching and Ф15 ～ 40mm during oil quenching. In addition to quenching and tempering, this steel is also suitable for cyanidation and induction hardening. The cutting performance is better. When the hardness is HB174 ～ 229, the relative cutting workability is 60%. 40Cr alloy steel is suitable for making medium-sized plastic molds.

After hot extrusion, the grains of the alloy wear-resistant steel plate are significantly refined, dendrites and network structures are broken, and the grain size and the distribution of precipitated phases in the alloy are more uniform to generate Al2Y and Al3Y phases distributed within and along the grain boundaries , The hardness is significantly improved, the mechanical properties are significantly improved, the deformation strengthening effect is more significant, and the corrosion resistance of the Q235D carbon steel plate sheet, alloy wear-resistant steel plate is significantly improved.

A335 P22 steel pipe belongs to ferrite alloy steel nominal pipe for high temperature use. Chemical composition of A335 P22 steel pipe: C 0.10-0.20, Mn 0.30-0.80, P ≤ 0.025, S ≤ 0.025, Si 0.10-0.50, Mo 0.44-0.65. Mechanical properties of A335 P22 steel pipe: tensile strength 415mpa, yield strength 205 MPa. Q235D carbon steel plate sheet, A335 P22 steel pipe is characterized by good process performance, less sensitivity to the heating temperature of heat treatment, good welding performance, good plasticity, and low strength, especially the high temperature rupture strength is lower than 12Cr1MoV steel. When used at the same temperature and stress, its wall thickness is about 30% thicker than 12Cr1MoV Steel.
